So - I won a laptop but I need help!

So.. I took part in the Dell Urban Challenge ( https://www.yoursishere.com ) this past weekend in Downtown Dallas.  I only was going because friends from my MINI Club were, and it was something to do Saturday Morning/Afternoon.

Well up to 500 teams could register in Dallas but when the time came for the Scavenger hunt to start, only 28 teams showed up.  We were split into 8 different colors so our changes were pretty much 1 in 3 to win.

My team came in and we won!  We were third overall and Metroplex MINI took 3 out of the 8 team wins!

Anyways.. They say we are to get vouchers for our free laptops, the affidvait states it is a "Dell Inspiron 1521" valued at $1,253.

So.. I guess I need everyones help..  I need to build a notebook that will run fast and smooth and decently with a few games I guess.. I do need a better battery then the standard one, and I would want to aim for a better warranty due to it being a notebook (bad experiences with screens on my end).

I know I haven't gotten my voucher and deals may change, but any help would be great.. Kinda at work so I cant get my exact spec down but was looking for some advice! 

Thanks guys.

EDIT:  This is what I came up with (Bleh its not a Dual Core Notebook)
